First Claim
Patent Images
1. A method for reconfiguring tissue of a hollow organ within the body of a patient, comprising:
- positioning an anchor delivery device in proximity to an external surface of the hollow organ;
forming a first tissue fold and a second tissue fold on the external surface of the hollow organ such that an invaginated portion of the hollow organ located between the first and second tissue folds is invaginated within the hollow organ;
deploying a first anchor of a first anchor assembly from the anchor delivery device into the first tissue fold and a second anchor of the first anchor assembly from the anchor delivery device into the second tissue fold, with the first and second anchors being connected to one another by a connecting member; and
moving at least one of the first anchor or second anchor along the connecting member to thereby decrease the distance between the first and second anchors and to approximate the first and second tissue folds.

Abstract
Devices and methods for forming and securing tissue folds and elongated invaginations in gastric tissue are used as a treatment for obesity. In several embodiments, a plurality of tissue folds is formed along the greater curvature of the stomach using laparoscopic tissue anchor deployment devices. Additional embodiments include various combinations of tissue folds, elongated invaginations, and other reconfigurations of stomach tissue using laparoscopic devices or laparoscopic devices in combination with endoscopic devices.
